Read the GVW printed on the door jamb sticker. That will tell you what the max Gross Vehicle Weight is for that truck.
1975-1979 the F-150 was considered a heavy half. It had a higher GVW than the F-100, mainly to get around the smog requirements imposed on the lighter GVW trucks. In 1980, the GVW minimum was raised, and all F100/F150 were subject to the smog standards. By 1984, the F100 was dropped.

I thought the term "heavy half" was a chevy term?. Ford had their "lightduty" f250's, which would probably be considered the same thing.
If you have 8 lugs holding the wheels on, but do not have a large piece sticking way out the center of the rear wheels, then you have a lightduty f250.

Actually, heavy half was GMC, chevy called it "Big 10". Ford chose the F-150 as it's higher GVW 1/2T designation.
I believe the original GVW cutoff for emission standards was around 5450 LBS, hence the early F-150 had 5500 LB or higher GVW.

the 6100lb GVW F-150 is the heaviest 1/2 available at that point in time. if you look at your rear suspension there will be an extra leaf spring bolted on top of the pack and there will be a set of tabs on the frame for that spring to hit.
